The Hubble Space Telescope Survey of M31 Satellite Galaxies. IV. Survey Overview and Lifetime Star Formation Histories

The Astrophysical Journal
From >1000 orbits of HST imaging, we present deep homogeneous resolved star color–magnitude diagrams that reach the oldest main-sequence turnoff and uniformly measured star formation histories (SFHs) of 36 dwarf galaxies (−6 ≥ M _V ≥ −17) associated with

The γ Dor stars as revealed by Kepler: A key to reveal deep-layer rotation in A and F stars

EPJ Web of Conferences, 2017
The γ Dor pulsating stars present high-order gravity modes, which make them important targets in the intermediate-and low-mass main-sequence region of the Hertzsprung-Russell diagram. Whilst we have only access to rotation in the envelope of the Sun, the

The JWST Resolved Stellar Populations Early Release Science Program. V. DOLPHOT Stellar Photometry for NIRCam and NIRISS

The Astrophysical Journal Supplement Series
We present NIRCam and NIRISS modules for DOLPHOT, a widely used crowded-field stellar photometry package. We describe details of the modules including pixel masking, astrometric alignment, star finding, photometry, catalog creation, and artificial star ...

New Symbiotic Stars from LAMOST DR10 Spectra and Multiband Photometry

The Astrophysical Journal
The Symbiotic star (SySt) is a long-period interacting binary system, typically consisting of a white dwarf (WD) and a red giant surrounded by a nebula. These systems are natural astrophysical laboratories for investigating binary star evolution. In this

Spatially-resolved TRGB JWST Color–Magnitude Diagram as a Tool to Measure Fossil Stellar Metallicity Gradients in Disk Galaxies: NGC 628

The Astrophysical Journal
We use archival JWST/NIRCam images in the F115W, F150W, and F200W filters to measure the tip of the red giant branch (TRGB) magnitudes across the disk of the late-type spiral galaxy NGC 628.
